Melt the chocolate and coconut oil in the microwave in 30 second increments until completely melted and smooth.
Fill a regular size muffin tin with paper liners. Use a tablespoon measure to pour a small amount of the melted chocolate (1-2 tablespoons) into the paper cups. Place the muffin tin in the freezer for around 10 minutes or until the bottom chocolate layer has hardened a bit.
Next, drop a small spoonful of the cashew butter (1-2 teaspoons) into the center of each cup and then a small spoonful of raspberry preserves (1-2 teaspoons) into the center of the cashew butter.
Top the cashew cups with the remaining chocolate (roughly 1 tablespoon).
If any cashew butter or raspberry preservers are sticking up, just gently press it down so each cup has a smooth top layer of chocolate. Freeze for one hour or until solid. Store in the freezer.
